摘要
BACKGROUND: The Cleveland Clinic Colorectal Cancer Quality of Life Questionnaire was developed in response to the need for a new, fast, and comprehensive tool for evaluating quality of life in patients who have colorectal cancer. Available surveys such as the SF-12, SF-36, Functional Assessment of Cancer Therapy-Colorectal, and European Organization for Research and Treatment of Cancer are either too general to be informative or too lengthy to complete. OBJECTIVE: The aim was to validate the Cleveland Clinic Foundation Colorectal Quality of Life Questionnaire. DESIGN: Data were obtained as part of a prospective randomized controlled trial. SETTINGS: This was a worldwide multicenter study with 2 domestic and 5 international locations. PATIENTS: This study randomly assigned 190 patients between the ages of 18 and 80 undergoing surgery for low rectal cancer. Of those randomly assigned, 142 with partially complete surveys were analyzed for selection bias and acceptability, and 95 with complete surveys were analyzed for survey validity. INTERVENTIONS: Patients received either a J-pouch, side-to-end anastomosis, or straight anastomosis. MAIN OUTCOME MEASURE: The study evaluated survey validity measures such as standardized Cronbach alpha for internal consistency and Spearman correlation coefficients for construct validity, convergent validity, and responsiveness. Univariate analyses were used to assess discriminative validity. RESULTS: Sufficient acceptability, construct, and convergent validity and responsiveness were achieved. All scores showed great internal consistency (Cronbach alpha >0.8). Superior discriminative ability was demonstrated by significant differences (p < 0.05) in 2 of 7 scores between neoadjuvant treatment groups, and in 6 of 7 scores between complication groups, none of which were detected by the SF-12 or Functional Assessment of Cancer Therapy-Colorectal surveys. LIMITATIONS: Limitations included a small sample size, cultural differences, and failure to assess test-retest ability of the questionnaire. CONCLUSIONS: The Cleveland Clinic Colorectal Cancer Quality of Life Questionnaire is an efficient and reliable quality-of-life measure that better incorporates factors specific to colorectal cancer surgery.

REDUCIENDO LA CARGA AL PACIENTE Y MEJORANDO LA CALIDAD DE DATOS CON EL NUEVO CUESTIONARIO DE CALIDAD DE VIDA EN CaNCER COLORRECTAL DE CLEVELAND CLINIC (CCF-CAQL) ANTECEDENTES: El cuestionario de calidad de vida en cancer colorrectal de Cleveland Clinic se desarrollo en respuesta a la necesidad de una herramienta nueva, rapida e integral para evaluar la calidad de vida en pacientes con cancer colorrectal. Los cuestionarios disponibles como SF-12, SF-36, FACT-C y EORTC son demasiado generales para ser informativas o demasiado largas para completar. OBJETIVO: El objetivo fue validar el cuestionario de calidad de vida colorrectal de la Cleveland Clinic Foundation. DISENO: Los datos se obtuvieron como parte de un ensayo prospectivo aleatorizado y controlado. ESCENARIO: Este fue un estudio multicentrico mundial con dos sedes nacionales y cinco internacionales. PACIENTES: Este estudio aleatorizo a 190 pacientes entre las edades de 18 y 80 sometidos a cirugia por cancer rectal bajo. De aquellos aleatorizados, 142 con encuestas parcialmente completas se analizaron para determinar el sesgo de seleccion y la aceptabilidad, y 95 con encuestas completas se analizaron para determinar la validez de la encuesta. INTERVENCIONES: Los pacientes recibieron un reservorio en J, anastomosis latero-terminal o anastomosis termino-terminal. PRINCIPAL MEDIDA DE RESULTADO: El estudio evaluo medidas de validez de la encuesta, como el Alfa de Cronbach estandarizado para la consistencia interna y los coeficientes de correlacion de Spearman para la validez de construccion, la validez de convergencia y la capacidad de respuesta. Se utilizaron analisis univariados para evaluar la validez discriminativa. RESULTADOS: Se obtuvo suficiente aceptabilidad, construccion, validez de convergencia, y capacidad de respuesta. Todos los puntajes mostraron una gran consistencia interna (alfa de Cronbach > 0.8). Una capacidad discriminativa superior fue demostrada por diferencias significativas (p < 0.05) en dos de siete puntajes entre grupos de tratamiento neoadyuvante, y en seis de siete puntajes entre grupos de complicaciones, ninguno de los cuales fue detectado por SF-12 o FACT-C. LIMITACIONES: Las limitaciones incluyeron un tamano de muestra pequeno, diferencias culturales y la falta de evaluacion de la confiabilidad test-retest del cuestionario. CONCLUSIONES: El Cuestionario de Calidad de Vida en Cancer Colorrectal de Cleveland Clinic es una medida de calidad de vida eficiente y confiable que incorpora mejor factores especificos asociados a la cirugia de cancer colorrectal.
